Hi, i noticed when building with Turbopack, this warning pops up:

 ⚠ Support for Turbopack builds is experimental. We don't recommend deploying mission-critical applications to production.

- Turbopack currently always builds production sourcemaps for the browser. This will include project sourcecode if deployed to production.
- It is expected that your bundle size might be different from `next build` with webpack. This will be improved as we work towards stability.
- This build is without disk caching; subsequent builds will become faster when disk caching becomes available.
- When comparing output to webpack builds, make sure to first clear the Next.js cache by deleting the `.next` directory.

Specifically

Turbopack currently always builds production sourcemaps for the browser. This will include project sourcecode if deployed to production

Does this mean it is client code or server code that would be available from the browser?

Thank you.
